Laundry wash water recycle system comprising a repressurization pump in fluid communication with a storage tank containing previously used wash water for pumping the used wash water sequentially through a lint filter, a cyclone, and a multi-media filter disposed in sequential series wherein the self-cleaning lint filter in sequential series combination with the cyclone removes insoluble solids with the multi-media filter providing a final filtration for obtaining an output of pressurized double filtered cyclonically processed water. An advanced oxidation combination is introduced into pressurized double filtered cyclonically processed water and mixing occurs for producing a double filtered cyclonically processed advanced oxidation treated water that is communicated to a clean water storage tank for providing on demand delivery to at least one washer and continuous delivery of a feedback flow to the inlet storage tank for providing constant recirculation of treated water through the system.

Apparatus (200) for the treatment of one or more substrates comprising a treatment chamber configured to receive a liquid medium and one or more substrates; a supply of a treatment gas comprising ozone; and one or more conduits to convey said treatment gas to a bubble generator (41) wherein said bubble generator is operable to form bubbles of said treatment gas in said liquid medium, wherein the apparatus comprises a multiplicity of solid particles (46). A method of treating one or more substrates, the method comprising agitating said one or more substrates in a treatment formulation comprising a multiplicity of solid particles, a liquid medium and bubbles of ozone.

Provided are an ozone sterilization washing machine and a method. The ozone sterilization washing machine comprises an outer barrel, an ozone generation device and a heating device, wherein an air inlet communicated with the ozone generation device is arranged at the bottom of the outer barrel, an exhaust hole is arranged at the upper part of the outer barrel and communicated with an exhaust pipeline, and the heating device is arranged in the exhaust pipeline to decompose ozone. According to the ozone sterilization washing machine, clothes are sterilized with ozone, and ozone which is not completely dissolved is thoroughly decomposed under a high temperature at a high decomposition rate; in addition, no catalyst is added, thus saving manpower and material resources.

Laundry apparatus (100) and methods for cleaning garments are provided, whereby the laundry apparatus (100) can provide one or more of: ultraviolet light, ultra-sound, ozone, carbon dioxide, and a surfactant source to clean the garments and includes an electronic control system (130) configured to transmit data corresponding to the laundry apparatus cleaning conditions and cleanliness of the garments wirelessly to an external computing device (132).

Electrolytic liquid generating device (1) includes laminated body (41) in which conductive film (46) is laminated to be interposed between mutually adjacent electrodes (44, 45), and electrolytic part (40) which electrolyzes liquid. Furthermore, electrolytic liquid generating device (1) includes a passage having inflow port (71) in which liquid to be provided to electrolytic part (40) flows and outflow port (72) from which electrolytic liquid generated in electrolytic part (40) flows out. The passage is formed such that liquid flowing direction (X) crosses laminated direction (Z) of laminated body (41).

Method and system for controlling a concentration of ozone is a washing machine to be at or below a target value so that a cumulative contact time of the ozone with laundry approaches a duration of time of an entire wash stage or cycle thereby ensuring killing of any infectious diseases. The method comprises supplying ozone to the washing machine, upon filling the washing machine, and supplementing the supplied ozonated water by supplying additional ozone to the wash machine during each wash stage or cycle, and controlling the supply of ozone supplied to the wash machine so that the concentration of ozone sampled or exhausting from the washing machine is controlled to be within a control band between 60% and 100% of the target value and the cumulative contact time of the ozone with the laundry is at least 60% of the duration of the entire wash stage or cycle.

A system is proposed for cleaning and sterilization wherein a carrier fluid is provided through a spray head having a mixing chamber, the flow of carrier fluid converted to a spray by the spray head. In the mixing chamber, ozone and ozone reaction products are mixed with the flow of carrier fluid to obtain a higher mixture of ozone and ozone reaction products in the carrier fluid immediately before the carrier fluid and ozone and ozone reaction products are dispensed as a spray.

Embodiments relate generally to methods and systems for bleaching textiles using ozone gas that incorporates a color removal step. In one example, there is provided a hybrid machine that incorporates certain features of a washer, but that also includes an integrated blower for gas distribution inside the machine. There is also provided an ozone dosing control system that allows for maintenance of a constant concentration of ozone in the machine. In one embodiment, the ozone output measured in grams/hour at this constant concentration in conjunction with the weight of product measured being treated may be referred to as the bleaching factor. There is further provided a wastewater dye removal step, in which ozone is used to clean the water and remove dyes and other colors that may be deposited via denim or other garments.

An aqua-ozone hygienization system is disclosed, including a tank configured to hold an item for treatment. The system enables user selection between three hygienization methods: a non-wetting atomized mist for deodorization, a wetting spray for disinfection, or an immersion for comprehensive purification, deodorization, and disinfection. A platform within the tank forms a water reservoir beneath it and provides a top surface for item placement. The system includes an electrochemical generator that produces ozonated concentrate liquid from water, supplied by a circulating pump drawing from the reservoir. A nozzle connected to the electrochemical generator is switchable between dispensing the ozonated concentrate liquid as either an atomized mist or spray. During operation, the liquid is either misted or sprayed onto the item, or accumulates on the platform to immerse the item, depending on the selected treatment method.

A system for washing laundry includes a cleaning fluid electrolytic hydrogen nano bubbles generation device for receiving tap water and electrolyzing the tap water to generate nano hydrogen bubbles and nano ion water or alkaline electrolytic water together as a cleaning fluid; a recycled water nano bubbles generation device for receiving tap water and water recycled by the system and generating ozone nano bubbles from the water, and at least one washing machine capable of performing pre-wash, main wash, or rinse. In the pre-wash or rinse, the recycled water nano bubbles generation device supplies the tap water having ozone nano bubbles to each washing machine through a pre-wash or rinse line. In the main wash, the cleaning fluid electrolytic hydrogen nano bubbles generation device supplies the main solution to each washing machine through, a cleaning fluid line.
